To all whom it may concern:

Be it known that I, FRANZ JosEPH SonmTTNER, a citizen ofthe United States, reslding at Germania, in the county of Potter and State of Pennsylvania, have invented certain new and useful Improvements in for Logging-Cars;

an I do herebiy declare the followin to be a full, clear, an exact description of the invention, such as will enableothers skilled in the. art to'which-itappertains to make and My invention relates to loggingcars, but

stakes forthe. release and discharge of lo s For its object this invention contemplates the productionof a bolster e uipment which is at once simple, cheap, an durable in its construction, easily manipulated and efficlent. in itso eration.

As a furt 1.61 object this invention contemplates the production of means whereby logging cars are more-readily and securely loa ed than heretofore, means whereby safe transportation of a cargo of logsis insured, means whereby the use and vexatious annoyances of logging chains is avoided, and what is of even greater importance, the lives and limbs of employees protected.

'The invention will behcreinafter particularly described and pointed out in the claims following. r

In the accompanying drawin s which form part of this application and w ereon corresponding reference numerals indicate like parts in the several views: Figure 1 represents in end elevation one complete bolster with its'trip stakes in position for loading, the figure being broken away at its center for economy of s ace upon thesheet. Fig- 2 is a longitudina sectional view of one bolster broken centrally as in Fig. 1, and taken upon the line {IF--27 of Fi 3. Fig. 3 is a horizontal section, also bro en away centrally, and taken on the line 7 of Fig. 2. Fig. 4 is a bottom plan view of the trip stakes shown in Figs. 1, i2 and 3, and. Fig. 5 is a modified form of trip stake in side elevation.

Reference being had to-the drawings and 5 numerals thereon, 1, 1 indicates the side sills of bolster, and 2 the intervening space- E timber or filler, while 3, 3 indicate space 5 blocks at. ends of the structure these parts 1, a

2 and 3 constituting the body'of the bolster and securely bolted together as shown. By this arran ement two end wells or recesses 4, 4 are re need as a suitable housing for the mova le operating elements of my invention. Said wells or recesses 4, ,4 are faced and remforced by sheet metal wear plates 5, 5 flanged at their outer ends over sills 1, 1 as best shown by Fig. 3.

The bolsters at opposite ends of a-car' are opposite ends of each bolster are the same, so that-a description of one end of one bolster will be understood to apply to both and is sufficient for present purposes.

' J ournaled in each well 4 be'tween plates .3,

5 which also serve as guide plates therefor is an ejector 6 rpreferably of cast steel, having a substantia y angular spur or projecting base 7, pivotally mounted as upon a through bolt 8 near its base and provided upon its inner edge with a projecting fin 9 .as best shown by Fig. 2. Pivotally connected to said fin 9 is one member 10 of a toggle lever, bifurcated at both ends and at its inner end ivotally connected to the other toggle member 11 which latter, in turn' is pivotally mounted upon a through bolt 12. toggle 10, 11 is connected a floating lever 13 also preferably bifurcated at both ends and To the the other, and likewise at its lower end connecting with a short rocklever 14 'kevcd upon a rock-shaft 15 passing the projecting end of said shaft 15 at the side of one sill 1, is keyed a trip-lever 16 protected by a flanged shield 17 above, and fitted at its upper end with a trip-rod 15 ex tending to the oppositeend ol the bolster, as Figs. 1 and-3. The said trip-rod 18 is guided in suitable eyes or staples 1S), and terlnirni-tes in a pull-handle 20, adapted to be secured in normal or locked position over a staple or eye-bolt 21 by agency of a pin 22 or a padlock.

Atopposite ends ol each bolster are tripstakes or log retaining stakes 23 made of any suitable material, but as a matter of con venienre preferably of hard wood. The lower end of stakes 23 are shear lied in a sheet steel outer raising 2-4 to protect them against wear and to facilitate the operation of ejecting them when desired. Casing '24 extends slightly above the bolster surface, and at its lower end is broken by side openings and a bottom openin 26 for purposes that will later appear. hese stakes are loosely ywhen in. o erative position as shown at the single beneath said slots 29 resting in suitable a cargo of logs for the mill, or other destina- Upon arriving at its destination a car fitted ejector 6 upon its pivotal support h. Simulchained or otherwisesecured to their respective bolsters as at 2.7 to prevent loss, and

left end 0' Fig. 2, stand vertically between the inner edge of space block 3 and the plane outer surface of the oscillatory ejector 6, the angular spur base 7 projecting -beneath. 4

The surface of be ster is covered by a plate of sheet iron 28. slotted centrally at its ends as at 29 to permit the introduc tion. and ejectment of trip-stakes 23; while guides (not'shown) on the surface of sills 1, 1 are reciprocating covers 30 or partial closures for said slots 29. These covers30 are automatic in their action being connected to the in 9 of ejector 6 by a rigid connecting rod 31 as shown by'Fig. 2.

This being a description of my invention, its operation is as follows: The car to be loaded is first fitted with trip-stakes .13 as shown by Fig. '1, an ordinary log-loader u )OD. temporary tracks upon the floor of an at jacent car of a logging train is next backed into osition for service as usual, logs are then oaded between corres onding stakes 23 of both bolsters, said sta res'being locked and securely retained in their normal or vertical positions by the alinemcnt of-toggle members 10, 11 and their actuating mechanism. 'Ihus tio'ns, without the use of log loading chains, may be transported withsafety regardless .of the usual rough conditions of logging roads.

with my improved trip-stakes and bolsters is speedily and safely unloaded as follows: Engaging the pull handle of-trip-rod 18, with the hook member of an ordinary pike lever (not shown), the operator forcibly re ciprocates said rod, causing a' partial rotation of rock-shaft 15 by agency of the intervening trip-lever 16. As a consequence, the lever 14 keyed upon and moving with shaft 15 pulls downward upon floating lever 13 disturbing the locking alinemcnt of toggle members 10, 1.] whereupon-tho latter assume the position indicated at the right hand end of Fig. 2-, thus tilting the corresponding taneously the corrcsponding slides are withdrawn, and the corresponding tripstakes 23 released from their normally clamped and locked positions are quickly clevatedby the underlying spur 7. Aided now by the lateral pressure of the load, stakes 23 unlocked as aforesaid are instantly cjccted thus relcasing the logs upon the opposite side of the car from that occupied by the operator, thereby insuring his safety.

During the tripping operation aforesaid slides 30 upon the discharging side of the'car are :uitomatically opened to facilitate ejectmeat of the stakes 22%, but at all other times they stand closed for the purpose of excludl ing foreign matter from their respective wells 4, and for like purposes the Hanged over and above the .in its preferred form and arrangement it should e noted that-I do not coni'inc myself thereto, as various changes in' the arrangement, construction and combination of parts may be made and substituted for those herein shown and described without departing from the spirit andteachings of my inven tion. For example, my improved bolster may be economically manufactured entirely from structural iron flanged as usual for purposes of strength and lightness. The tripstake 23 may if desired be cast or formed solid, as indicated by modified Fig. 5, and in like manner other contemplated changes will readily be suggested to persons skilled in the art. 1
